A student ran the following reaction in the laboratory at 338 K:
2 NO(g) + Br2(g) 2 NOBr(g)
When she introduced 0.116 moles of NO(g) and 9.28E-2 moles of Br2(g) into a 1.00 Liter container, she found the equilibrium concentration of NOBr(g) to be 7.85E-2 M.
Calculate the equilibrium constant, Kc, she obtained for this reaction.
